Just finished swapping a 12bolt into my '88 Burb R10, put a full leaf pack (in place of a dearched set of 3) and flip kit. Now, I'm noticing that the rear shocks, Belltech 2208HF, are hitting the frame. It actually rides great and you don't notice an issue until you take off from a stop, you hear a clunk.
Any ideas?

Just a wild ass guess, but doesn't axle flip drop require shock extenders?

I think so, but I'm using drop shocks, so it's my understanding that they're not needed.
I made some adjustments the rear end tonight and it seems to be a lot better. Plan on putting some more miles on it tomorrow and see it does.

Nope. I did it on mine and there is plenty or room. The extenders are used to keep the same shock angle for better ride.

Ok... Update. Looking for advice
The burb has been riding pretty good, but I noticed the other day that the rear end is sitting too far forward (wheels not centered in the wheel well). So after some research, I realized that the block that came with flip kit was turned around backwards hope for center spring bolt was towards the rear of the burb. Tonight, I turned them around, wheels much closer to center of the the wheel wells. However, now the rear bounces like crazy (think old lincoln with busted air bags). The driver side shock, looks to be at the correct, or close to the correct angle, but the passenger shock looks like it's laid down more (like the rear end needs to come forward on that side). I'm at loss, any advice other than rolling the damn thing in a pond.

Is one of your springs sets on backwards? Some springs are not Centered.

No advice on the springs/blocks but did you have to use a different u-joint when you swapped the 12 bolt for the 10?

I wondered that myself, but they look to be set the same way. Longer side forward

I thought the yoke may be different. Do you remember the part number of the u-joint?

Update... Now struggling with shock extenders. Come to find out, the rear end must be out of a 4x4 and had different shock mounts... Who knew. Any ideas for shock extenders that will fit?

Same problem almost 10yrs ago... http://67-72chevytrucks.com/vb...read.php?p=8824206#post8824206
